The BM01 is a mould ((without pressure sensor and transmission control system)) designed for studying solid-state lithium-ion batteries (SSBs). The device tests and studies the electrochemical properties of solid-state batteries with different electrolyte materials by simulating the structure and working principle of SSBs.

BM01 mold includes 1 stainless steel outer frame, 2 mold steel ejector rods, 2 poles, 2 fastening knobs, 2 O-rings, 2 protective covers and 1 ceramic insulating sleeve, PPS material protector.

According to the diameter of the sample loading part, they can be divided into BM01-10, BM01-12, BM01-15, BM01-20, with diameters of 10mm, 12mm, 15mm and 20mm respectively. Other specifications can be customized.

This mold can be used in conjunction with the BS01 Multi-Channel Solid State Battery Pressure Test System.

Take BM01-10 as an example

Internal Specifications: (with PPS sleeve) diameter 40mm. The cavity diameter is 10mm. Overall height 70mm

Overall specifications: The outer diameter of the device is 90mm, and the total height of the screw rod is 130mm

Features

- High Stability and Good Sealing Ability

- High Pressure Bearing Capacity (up to 300 Mpa)

- Favorable Handle Operability and Compatibility

- Wide Using Temperature Range (-40~200℃)

- Dimensions (mm, BM01-10 with stainless steel outer frame): 100 L x 100 W x 130 H (mm)

- Weight (kg, BM01-10 with stainless steel frame): 2kg

Pressure test

1. The maximum pressure can reach 400 Mpa

2. The pressure of the press to 1 ton is approximately equal to the pressure of 125 Mpa

Advantage

1. Protective kits, insulating sheets are made of PPS

2. Double sealing ring technology to better ensure mold sealing. (The pressing sealing ring is Teflon, compared with peek, it fits the sealing ring better and makes the sealing better)

3. Good materials and low price

4. Pressure column, gasket, mold bottom, grinder treatment, better plane, and smoothness

Notice:

1. The assembly of solid-state batteries, the whole process needs to be operated in a glove box

2. Mold pressure test, the pressure is about 80-150MPa, if there are lithium or indium chips, the pressure should be reduced to less than 80Mpa

Solid-state battery insulation mold description

1. The mold and the powder tablet machine are used together

2. The insulating mold is made of PPS material to protect the outer parts and ceramic (or PEEK) inner liner. It has the characteristics of high hardness, good toughness, excellent finish, accurate precision, long life, and easy replacement of wearing parts.

Installation and pressurization process:

In the glove box, first place the die sleeve on the die bottom, and rotate the screw screw of the tablet press downward until it is against the pressing rod. After adding the required pressure, tighten the screw on the top of the transfer fixture again to achieve the effect of sealing and maintaining the pressure, remove the glove box and test in a normal environment. (You can also apply a small amount of vacuum grease or Vaseline to the gap between the pressing rod and the inner mold sleeve, and then take out the glove box for testing)

Precautions:

1. When using the mold, the limit of the maximum working pressure of the abrasive tool must be observed

2. Exceeding the working limit pressure will cause damage to the abrasive tool, and the maximum working pressure of the abrasive tool with different diameters is different

3. After the mold is used, the mold should be cleaned with alcohol and then cleaned with alcohol. Grease is applied to the ejector rod, and a rubber sleeve is used to protect the surface to prevent oxidation and corrosion of the surface, and then placed in a dry and airtight environment for maintenance.

4. The solid-state battery test abrasive is used for the characteristic test of solid-state batteries. The insulating abrasive is clamped with a transfer fixture in the glove box, placed in the tablet press to a suitable pressure, and the screws on the fixed abrasive are tightened. Relieve the pressure, take out the transfer jig and the insulating abrasive together for testing.
